Churches have no obligation to offer disaster relief. Once a church gets relatively large, they focus more on obtaining profit and publicity over Christian traditions. If mega churches do decide to help, it would only be because they are benefiting in some way. I feel these days people put way to much faith in church institutions. People need to remember that churches are business. They make money based on their amount of followers.
